An international shipment that should be moving toward your customer can sit at the border for days without any clear update. For a small business, that pause is costly. It can disrupt cash flow, miss a launch window, and damage customer trust.
If you have ever wondered why a package would be held in customs, the answer usually comes down to a short list of recurring issues. Here are six common reasons international shipments get held at customs, and how to avoid each one.
1. Incomplete Or Inaccurate Documentation
Most border holds start with paperwork. A commercial invoice with the wrong value, a packing list that does not match the actual goods, or a missing country of origin certificate can stop a shipment fast. Customs officers rely on these documents to verify what is inside the box, so any gap forces a manual review.
Double-check every field before dispatch, and ask your freight forwarder to flag anything unclear.
2. Wrong HS Code Or Tariff Classification
Every product crossing a border needs a harmonized system (HS) code. Using the wrong one is one of the most common causes of customs clearance delay for small importers. The code decides the duty rate, the regulatory checks, and sometimes whether the goods are even allowed in.
Look up the code through your destination country’s tariff database, or work with a customs broker who handles your product category. Small classification errors lead to long holds.
3. Unpaid Duties, Taxes, Or Fees
If duties and taxes are not paid on time, your package will not move. Many small businesses ship under Delivered Duty Unpaid (DDU) terms without telling their customer, who are then asked to pay a fee before delivery. This adds confusion and can delay your customs clearance by several days.
Decide upfront whether you or the buyer will pay, and communicate it clearly. Landed cost tools from FedEx, DHL, and UPS make this easier.
4. Restricted Or Prohibited Goods
Every country has its own list of restricted and prohibited items, and the list changes often. Cosmetics, supplements, certain electronics, plant materials, and some textiles often need permits or certifications. If your product falls under a controlled category and the supporting paperwork is not attached, the shipment will be held.
Check the destination country’s customs website before shipping, especially for first-time markets, and confirm what licenses or declarations apply.
5. Missing Filings For Food And Beverage Imports
If you ship food, drinks, or supplements into the United States, there is a separate FDA filing that must reach the agency before your goods arrive. Miss it, or submit it late, and the shipment is held until the paperwork catches up. Many first-time importers only learn this after their freight is already on the water.
Build the filing into your dispatch checklist, and confirm your customs broker handles it as standard.
6. Random Inspections And Risk-Based Holds
Even with perfect paperwork, customs can pull a shipment for inspection. Some holds are random, others are triggered by your importer history, country of origin, or product type. There is no way to fully avoid this, but consistent documentation, a clean compliance record, and using established carriers lower your risk profile over time.
If your goods are stopped, respond to information requests fast. A delayed reply usually means a longer clearance delay.
Plan Ahead And Spend Less Time Waiting
International shipping comes with friction points that every small business will eventually meet. The good news is that almost all customs holds trace back to fixable issues, whether that is cleaner paperwork, accurate classification, or making sure regulatory filings like FDA Prior Notice are submitted on time.
Build a pre-shipment checklist, work with partners who know your product category, and your shipments will spend more time moving and less time waiting at the border.
